SPLIGER FOR POWER LINES.

Application filed May 26, 1926. Serial No. 111,792.

This invention relates to a device for splicing power lines, one of the objects being to provide simple and efiicient means whereby the connected wires can be drawn taut and 6 properly held in such a way as to prevent leakage of current at the joints, it being also possible to use the splicer on trolley wires without interfering with the movement of a trolley wheel thereover.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings, Figure 1 is a side elevation of the splicer in engagement with two wires.

Figure 2 is a plan View thereof. Figure 3 is a section on line 3-3, Figur 2, the wires being shown in elevation.

Fi ure 4 is a section similar to Figure 3 but s owing the splicer filled with solder.

Figure 5 is a section on line 5--5, Figure 1. Referring to the fi ures by characters of reference 1 and 2 designate power wires having the ends rovided with right-hand and left-hand t reads respectively and 35 adapted to be engaged by a sleeve 3. This sleeve has a central recess 4 into the ends of which open bores 5 extending into the sleeve from the res ective ends thereof, these bores being threa ed for engagement with the 40 threads on the respective wires 1 and 2 so that when the sleeve is rotated in one direction the two wires will be drawn toward each other. A slot 6 is provided in the sleeve and opens into the recess 4, this slot bein preferus ably formed with a de ression at t e outer end of one wall thereo as shown at 7. An 0 ening 8 is extended from the recess 4 to t e outer surface of the sleeve at a point diametrically op osite the slot 6. 00 If desired, an as shown in the drawings, diametrically o posed de ressions 9 ma e formed in the s eeve for the reception 0 the jaws of a wrench or other suitable tool by means of which the sleeve can be rotated readilyfor the purpose of drawing the wires taut.

The splicer constituting the present invention can be used either for connecting power lines or for connecting trolley wires. In the latter event it is preferred to have the sleeve 3 much longer than is necessary where ordinary power lines are joined. By having the sleeve of considerable length and with long tapered ends, trolley wheels can pass into engagement therewith and travel therealong 05 without danger of jumping from proper position. In the form shown in the draw-' ings and which is designed for connecting power lines, the ends are tapered as shown at 10 thereby reducing the weight of the splicer and at the same time practically eliminating abrupt terminal shoulders.

In using the splicer the same is laced in engagement with the threaded en s of the wires and is rotated so as to draw the wires toward each other. After the wires have been made sufficiently taut the sleeve is sup.- ported with the slot 6 uppermost. Melted solder is then poured into the slot 6, being properly guided thereto by the wall of the recess 7. This solder will enter and fill the recess 4, o ening 8 and slot 6 and will roe duce a tig t connection between the wires, preventing the sleeve from working loose and also preventing a drop in voltage. In Figures 4 and 5 the solidified solder in the sleeve has been indicated at 11.

When it is desired to disconnect the wires the splicer is heated. The solder will thus be caused to melt and will flow from the recess 4 and the slot 6 through the opening 8.

What is claimed is:

A splicer for connecting trolley wires and the like including an elongated substantially cylindrical sleeve having tapered ends, there bein a central recessin the-sleeve extending longitudinally thereof, said sleeve having a threaded bore extending from each end thereof to one end of the recess, the bores being adapted to receive the threaded terminals of the wires to be connected, there being an elongated slot opening into the top of the recess and terminating short of the ends of the recess, said slot constituting means for liquid state, the outer end of the slot being provided with a flared portion for guiding liquid solder into the slot and recess. I

In testimony that I claim the foregoing as 10 my own, I have hereunto affixed my sig' nature.
